New 2024 Ignition Interlock Device Enhancement Law

According to Senate Bill 0258, drivers using an Ignition Interlock Device (IID) will find that their devices now employ global positioning system (GPS) technology starting January 1,  2024.  This technology will geotag the motor vehicle’s location whenever an initial startup test, a random retest, or a skipped test occurs, or when circumvention of the device is detected.  The law also includes a provision prohibiting the GPS technology from being used for continuous tracking of the vehicle.

This amendment to T.C.A. Section 55-10-411 has been reported by some news sources such as to help prevent DUI offenses by reflecting, “an evolving approach to dealing with DUI incidents, prioritizing public safety while respecting individual privacy.”  This author holds a different opinion, however. Based on issues that have arisen in the courtroom, this author believes the addition of GPS to the ignition interlock devices was implemented so that if it a driver or other party violated T.C.A. §55-10-417(h)(1), prosecutors may establish venue (the place where judicial authority exists) in their particular county.

Generally, T.C.A. §55-10-417(h)(1) prohibits tampering with, or in any way attempting to circumvent the operation of a functioning ignition interlock device that has been installed in a motor vehicle. This is a separate crime that carries a Class A Misdemeanor punishment with a minimum mandatory jail time of 48 hours.

For instance, if a driver who had been drinking a lot convinced a sober person to blow into the vehicle’s IID so that the impaired driver could operate the vehicle, the prosecutor would be obligated to show that the violation (of both parties) occurred in the county of prosecution in order to obtain a conviction. Otherwise, a prosecutor would not be able to easily prove where the alleged crime occurred.
